BERNARD REIN, OF DETROIT, MICHIGAN, ASSIGNOR TO THE UNION HEATER SUPPLYCOMPANY, OF SAME PLACE.

BRAZlNG-FURNACE.

SPECIFICATION forming part of Letters Patent No. 552,330, dated December31, 1895.

Application filed April 22, 1895.

To all whom it may concern.-

Be it known that I, BERNARD REIN, a citizen of the United States,residing atDetroit, in the county of \Nayne and State of Michigan, haveinvented certain new and useful Improvemerits in Brazing-Furnaces, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The invention consists in the construction of I o a vapor-b urningbrazing-furnace, comprising two oppositely-arranged fire-pots adjustablyarranged in relation to each other so that they may be made to approachto or recede from the work, and so that the angle at which the fire isdirected upon the work may be varied as desired.

The invention further consists in the construction, arrangement andcombination of the various parts, all as more fully hereinafterdescribed.

In the drawings, Figure 1 is a perspective view of my device, showing infull and dotted lines different positions of the firepots. Fig. 2 is avertical central section through one of 2 5 the fire-pots.

A is a tank for containing the gasoline or other liquid fuel, this tankbeing provided with a s uitable nipple B,by means of which air underpressure may be pumped into it to force 0 out the liquid. The top of thetank may be provided with an inlet or mouth closed by a removable plugor cap, as indicatedat B.

O is the discharge-pipe therefrom, this pipe leading to the bottom ofthe tank. This pipe 3 5 has two horizontal branches D D, each having aswivel-joint E therein, in which are supported the vertical pipes F F,forming an extension of the branches of the supply-pipe. At the topthese vertical pipes are formed into the horizontal cylindrical coils G,at the outer end of which is the cross-head H. This head carries twovalve-controlled jets I, which discharge into the chamber J within thecoils, which forms the combustion-chamber of the fire-pot.

5 This chamber I preferably inclose by a cylindrical cap or hood K,having a lining of asbestos paper or other similar non-combustiblenon-conductor to prevent the burning out of the hood. The end or head ofthe hood I pro- 5o vide With apertures at opposite the jets, and withair-inlet apertures 19 around the edges to Serial No 546,684. (Nomodel.)

admit air for combustion. These two firepots being arranged oppositely,oil fed to the coils from the tank will be vaporized therein anddelivered from the jets into the chambers 5 5 J, where it will be mixedwith a proper amount of air, and the force of the jet will throw theflame from the fire-pot outward toward the opposing fire-pot, the twoflames meeting and causing intense heat at the meeting-point, at whichthe work is held. These fire-pots may be moved by turning them on theswivelj oints,causing them to approach or recede, and changing the angleat Which the flames come together and strike the Work. The work may beheld upon the work-holding arm L, adj ustably supported in the tubularstandard M, which is supported on the pipe 0, as shown. Either one ofthese fire-pots may be used separately if desired, and they can beturned into any desired relation to their support from the vertical t0the horizontal, as shown in dotted lines in Fig. 1, the friction of theswivel-joint being sufficient to hold them in their adjusted positions.

I may and preferably do provide a tubular standard 0 centrally betweenthe fire-pots, in which is adj ustably supported the standard 0 carryingthe deflector-plate P at its top, which acts to prevent too great avertical circulation of the air when the two furnaces are used together,and enables me to get a somewhat hotter fire than if the furnace is usedwithout it.

While I have shown the two hoods inclosing the coils, it is evident thatas these coils are 7 made as closed coils they alone will form thecombustion-chamber if desired.

What I claim as my invention is-- 1. In a brazing furnace, thecombination of the tank, the tubular standard thereon, hav- 9o ing twovbranches, the swivel joints in said branches, pipes extending up fromsaid joints, coils in said pipes, hoods inclosing said coils, and vaporburners discharging toward each other through the hoods, substantiallyas de- 5 scribed. I

2. In a brazing furnace, the combination with the supply pipe, a pipeconnected therewith, a coil in the latter pipe forming the combustionchamber for the burner, an inclosing IOQ hood for said coil providedwith an end plate, the end of the coil passing through said end plateand provided with jet burners dischargin g into the combustion chamberthrough apertures in the end plate, substantially as described.

In a brazing furnace, the combination of the supply pipe, the branchpipes connected therewith, said pipes being coiled near one end, hoodsinclosing said coils, jet burners at the end of each branch pipesituated Without the hoods and discharging into and through said coilstoward each other, substantially as described.

4. In a brazing furnace, the combination of the oppositely arrangedcombustion chambers, the bracket between the same, the Verticallyadjustable deflector plate between and below the plane of the burners,substantially as described.

In testimony whereof I affix. my signature in presence of two witnesses.

BERNARD REIN.
